Your goal
Arrange 1 to 15 in reading order with the empty square at the bottom right. The feedback beside the game helps you follow the round. Try to explain the aim in your own words.
Step by step
- Select a tile directly beside the empty square.
- The tile slides into the gap; diagonal moves are not allowed.
- Use Undo to step back one move.
- Finish the ordered board, or choose New puzzle.
Controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Read the example below alongside these instructions.
A useful example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Compare this with the rule that governs the move. Keep the controls nearby.
Watch out for this
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
